THROMBOSIS OF THE INFERIOR VENA-CAVA - AN UNUSUAL PRESENTATION OF PROTEIN-C DEFICIENCY

In children, venous thrombosis is uncommon and this is true particular ly for one of the inferior vena cava. Recurrent superficial venous thr ombosis is a well-recognized presenting symptom of Protein C deficienc y but thrombosis of the inferior vena cava as the initial manifestatio n of this condition has only rarely been reported. We present a case o f a 13-year-old boy in whom the first indication of Protein C deficien cy was an isolated thrombosis in the intra-hepatic inferior vena cava noted on a routine ultrasound examination.
